All our applications programs and data are on the 780 disks. The problem surfaces in this nature. When we run a I/O type job on the micro-vax the Interrupt stack on the 780 goes to 60-70% of the cpu cycles If a cpu intensive job ie compile/links is run on the micro-vax the effect is not as great. Has anyone else experienced a similar problem? If so any suggestions to correct it. Thanks in advance Steve Smith BITNET: SSMITH@STMARYS.BITNET
